Is there anyway to change a part's size using tween service?

I have tried using CFrame and all it does it position the part, is there any way to change the size with tween service?

local db = false

game.ReplicatedStorage.Remotes.Lockdown.OnServerEvent:Connect(function()
	if db == false then
	db = true
		local TweenService = game:GetService("TweenService")
		local tweenInfo = TweenInfo.new(1, Enum.EasingStyle.Linear, Enum.EasingDirection.InOut)
		
		game.Workspace.LockDown.Part1.Transparency = 0
		game.Workspace.LockDown.Part2.Transparency = 0
		game.Workspace.LockDown.Part3.Transparency = 0
		game.Workspace.LockDown.Part4.Transparency = 0
		
		local tweenPart1 = TweenService:Create(game.Workspace.LockDown.Part1, tweenInfo, {CFrame = game.Workspace.LockDown.Part1End.CFrame})
		local tweenPart2 = TweenService:Create(game.Workspace.LockDown.Part2, tweenInfo, {CFrame = game.Workspace.LockDown.Part2End.CFrame})
		local tweenPart3 = TweenService:Create(game.Workspace.LockDown.Part3, tweenInfo, {CFrame = game.Workspace.LockDown.Part3End.CFrame})
		local tweenPart4 = TweenService:Create(game.Workspace.LockDown.Part4, tweenInfo, {CFrame = game.Workspace.LockDown.Part4End.CFrame})
		
		tweenPart1:Play()
		tweenPart2:Play()
		tweenPart3:Play()
		tweenPart4:Play()
	end
end)
